The reasons are all bad. The worst one being that it violates the Constitution. All you're saying is that you don't give a crap about what the Constitution says.
The Constitution allows for regulated capitalism, as does common sense, as does capitalism itself which doesn't exist without government.
And yes, unlike you, I deal with the real world. We don't live in 1789 so what actually worked for them then doesn't matter a damn today. Since they expected us to recreate the government to fit our needs, exactly what they did, they wouldn't be dumb enough to say you shouldn't have an FAA just because we didn't have one. They would have said, dummies, we didn't have ******* planes you morons...
